Talk about a bad case of cell phone addiction. Chinavasion describes this as the ultimate hands-free device, and for good reason: It's a tiny microphone designed to be embedded in the teeth.
If we weren't told otherwise, we'd swear this was an April Fool's prank. But the "Bluetooth Dentacom" is apparently for real, a "composite resin filling" that will "pick up sound and vibrations from your mouth to produce incredibly clear sound," according to GeekAlerts.
But take note of the distributor's advice: "All dental work should be performed by a qualified dentist. Chinavasion does not take responsibility for injury resulting from the installation of this product." We'll stick with the speakerphone for now.
